If you’re running a business, you already know that card processing fees add up fast. But where those fees come from (and how they’re packaged), isn’t always as clear as it should be.
That’s because every card payment passes through a chain of middlemen: banks, card networks, acquirers, and your payment provider. Each one takes a slice. But how those slices show up on your statement depends on your pricing model.
Choosing the right pricing model is crucial, especially if you’re in a high-risk industry where fees, declines, and compliance hurdles can dramatically impact your bottom line.
Most businesses use one of two: Interchange++ or blended pricing. But which one actually saves you more in the long run and is better for your business?
In this guide, we’ll walk you through both models, how they affect what you’re paying, the difference between interchange ++ vs blended pricing, and how to choose the one that makes the most financial sense for your business.
What is Interchange Plus Plus pricing (IC++)?
Interchange Plus Plus, or IC++, is a transparent pricing model that breaks down your card processing fees into three distinct parts:
Interchange Fee
These fees are set by card networks like Visa, Mastercard, and American Express.
They’re paid by your acquiring bank to the cardholder’s issuing bank for each transaction. The fees compensate the issuing bank for processing the transaction, managing risk, and preventing fraud.
Interchange fees vary based on:
- Card Type: Debit, credit, commercial, and rewards cards all have different rates. Commercial and credit cards usually cost more.
- Transaction Type: Card-present transactions (where the card is physically swiped or inserted) generally have lower fees than card-not-present (online) payments due to lower fraud risk.
- Merchant Category Codes (MCC): Affect fees, with high-risk categories typically facing higher rates due to increased fraud risk and regulatory scrutiny
- Region: Domestic payments are typically cheaper than cross-border transactions.
Typical fees range from 0.3–0.4% in Europe to around 2% in the US. These fees are set by the card schemes and are non-negotiable.
Scheme Fee (also called Assessment Fee)
Card networks charge these fees for using their payment systems and infrastructure. They cover network maintenance, security, and operational costs.
Scheme fees include:
- Assessment Fees: A percentage of each transaction, usually between 0.11% and 0.14%.
- Authorization Fees: A fixed cost per transaction authorization, often between $0.01 and $0.10.
- Network Access Fees: Charges to access the payment network, which can be per transaction or a flat monthly fee, ranging widely (e.g., $0.005 to $0.10 per transaction or $5 to $15 monthly).
These fees are standard across processors and generally non-negotiable, with minimal exceptions.
Acquirer Markup (the “Plus Plus”)
This is the margin your payment processor or acquiring bank adds on top. It covers the services and risks they take on to process your payments.
This markup includes:
- Processing Costs: Fees for transaction authorization, clearing, and settlement.
- Risk and Fraud Management: Investment in tools and services that keep your payments secure.
- Customer Support: Handling disputes, inquiries, and chargebacks.
- Compliance: Ensuring your transactions meet regulatory standards.
- Profit Margin: The processor’s earnings for providing the service.
Unlike interchange and scheme fees, this markup is negotiable. High-volume or low-risk businesses can often secure better rates here.
Interchange ++ vs Interchange Plus (IC+)
The main difference between Interchange++ (IC++) and Interchange Plus (IC+) is how card scheme fees are handled.
- Interchange++ (IC++): Each of the three fees are shown separately, giving you full transparency about what you’re paying.
- Interchange Plus (IC+): Combines the card scheme fees with the processor’s markup into one single fee. While interchange fees remain separate, this means you don’t see exactly how much the processor charges on top of the card scheme fees.
In short, IC++ offers more detailed transparency, while IC+ simplifies the pricing but hides some fee details inside the processing markup.
What is Blended Pricing?
Blended pricing is a simplified card processing pricing model that combines all fees into a single, flat rate per transaction.
Instead of breaking down costs like interchange fees, scheme fees, and processor markups separately, blended pricing bundles them together for easier understanding.
Here’s how it works:
- One Flat Rate: You pay a fixed percentage or fixed fee per transaction, no matter the card type, payment method, or network involved. For example, you might pay a flat 2.9% + $0.30 per transaction.
- Simplified Billing: Your monthly bill shows this single rate applied to your total processed volume, making it easy to predict your payment processing costs.
- Less Transparency: Unlike Interchange++, you won’t see the individual fee components or how much each party in the payment chain is charging. This can make it harder to identify where your money is going or negotiate better rates.
Blended pricing works best if you want simplicity and don’t mind potentially paying a bit more. For smaller or lower-volume businesses, it can save time and headaches.
But if your business handles lots of transactions or higher-value cards, this flat-rate approach might cost you more over time.
Interchange++ vs Blended Pricing: Key Differences
With a clearer understanding of what Interchange++ and Blended Pricing is, we can put them side to side and see where they actually differ:
Now, let’s unpack each one in more detail and which benefit it brings to your business.
Transparency
Interchange++ lays everything bare: you see the exact interchange fees, card scheme fees, and your processor’s markup as separate line items. This level of detail gives you full visibility into where your money goes.
Blended pricing bundles all these fees into one flat rate. It’s easier to understand at a glance, but you lose insight into the individual components, making it tougher to negotiate or identify hidden costs.
Cost Efficiency and Flexibility
Interchange++ rewards businesses that understand their payment mix and transaction types. Since fees vary by card type and transaction method, you can optimize for cost savings. Plus, you can negotiate markups as your volume grows.
Blended pricing trades flexibility for simplicity. You pay one set rate regardless of card type or transaction details. For low volume or straightforward sales, this can be convenient. However, it may cost you more if your transactions include higher-fee cards, or you process a lot of payments.

Business Suitability
Interchange++ is tailored for larger or higher-volume merchants who can invest time into managing and analyzing their fee structures. If your business handles diverse payment types or international cards, this model often delivers better financial results.
For high-risk businesses, Interchange++ shows exactly where fees are higher due to risk, giving you insight to manage costs. However, it requires expertise and active management,
Blended pricing shines for small to medium businesses that want to streamline operations and avoid the complexity of fee breakdowns. It’s also a good option if you want a predictable, “set and forget” approach.
For high-risk merchants, blended pricing usually includes a risk premium bundled into the flat rate. This means fewer surprises but potentially higher overall costs because the provider covers the risk internally.
Negotiability
With Interchange++, the markup portion is negotiable. If you bring a significant volume or low risk profile, you can push for better rates, saving more over time.
Blended pricing usually comes with a fixed markup bundled into the flat rate. This leaves little room for negotiation, especially as your business scales.
Cost Predictability
Interchange++ fees vary with transaction type and card category. That means your monthly costs can fluctuate, making budgeting a bit trickier. However, it also means you’re only paying what the transactions actually cost to process.
Blended pricing offers predictable costs. You pay the same flat rate on all transactions, which simplifies budgeting and cash flow planning. But that predictability might come at the price of overpaying for lower-cost transactions.
How To Choose The Right Pricing Model For Your Business
Choosing between Interchange++ and blended pricing can feel overwhelming, but it doesn’t have to be. Focus on what matters most to your business, and you’ll make the right call.
1. Know Your Transaction Volume and Mix
- High volume with diverse card types? Interchange++ usually saves you money by tailoring fees to each transaction.
- Smaller volume or simple payment types? Blended pricing offers predictability and ease.
2. Decide How Much Transparency You Need
- Want to see every fee broken down clearly and control costs? Interchange++ gives full visibility.
- Prefer simplicity and fewer surprises on your bill? Blended pricing keeps things straightforward.
3. Consider Your Resources and Expertise
- Got time and tools to analyze and optimize your fees? Interchange++ rewards active management.
- Need hassle-free billing and fewer details? Blended pricing reduces accounting complexity.
4. Evaluate Your Budgeting Priorities
- If you want to pay exactly what transactions cost, and don’t mind some monthly variability, Interchange++ fits.
- If stable, predictable monthly fees help your cash flow planning, blended pricing is the safer bet.
5. Don’t Forget Negotiation Power
- Large or low-risk merchants can negotiate better markups with Interchange++.
- Blended pricing markups are typically fixed, so less room to bargain as you grow.
6. Factor in Your Risk Profile
- If you’re in a high-risk business, Interchange++ shows you exactly where higher fees and risks lie, but you’ll need to manage those costs closely.
- Blended pricing simplifies fees but often includes risk premiums baked in, which can increase your costs without clear visibility.
Tip: If you’re high-risk, choose a payment orchestration platform that understands your industry and helps control fees, no matter the pricing model.
